c# - Linq to XML 查询返回字符串列表

Question

我有以下类(class)

public class CountrySpecificPIIEntity
{
    public string Country { get; set; }
    public string CreditCardType { get; set; }
    public String Language { get; set; }
    public List<String> PIIData { get; set; }        
}

我有以下 XML，我想使用 Linq-to-xml 查询并调整到上面的类中

            <?xml version="1.0" encoding="utf-8" ?>
            <piisettings>
              <piifilter country="DE" creditcardype="37" language="ALL" >
                <filters>
                  <filter>FIRSTNAME</filter>
                  <filter>SURNAME</filter>
                  <filter>STREET</filter>
                  <filter>ADDITIONALADDRESSINFO</filter>
                  <filter>ZIP</filter>
                  <filter>CITY</filter>
                  <filter>STATE</filter>
                  <filter>EMAIL</filter>
                </filters>
              </piifilter>
              <piifilter country="DE" creditcardype="37" Language="en" >
                <filters>
                  <filter>EMAIL</filter>
                </filters>
              </piifilter>
            </piisettings>

我正在使用以下查询，但我在处理最后一个属性(即 PIIList)时遇到了问题。

            var query = from pii in xmlDoc.Descendants("piifilter")
            select new CountrySpecificPIIEntity
            {
               Country = pii.Attribut("country").Value,
               CreditCardType = pii.Attribute("creditcardype").Value,
               Language = pii.Attribute("Language").Value,
               PIIList = (List<string>)pii.Elements("filters")
            };

            foreach (var entity in query)
            {
            Debug.Write(entity.Country);
            Debug.Write(entity.CreditCardType);
            Debug.Write(entity.Language);
            Debug.Write(entity.PIIList);
            }

我如何获取查询以返回一个列表，以便将其添加到 PIIList 属性中。

Answer 1

var query = from pii in xmlDoc.Descendants("piifilter")
select new CountrySpecificPIIEntity
{
   Country = pii.Attribut("country").Value,
   CreditCardType = pii.Attribute("creditcardype").Value,
   Language = pii.Attribute("Language").Value,
   PIIList = pii.Elements("filters").Select(xe => xe.Value).ToList();
};
